Describe about the Development and Assessment of a New Model For Frp Patch.
After reading the heading of the provided dissertation, the reader will first get confused as teh heading reads genetic programming in the simulation of frp-to-concrete patch-anchored joints. This signifies that the dissertation is based on the role of the genetic programming in the simulation of the frp-to-concrete patch-anchored joints where as in the abstract it is clearly mentioned that the dissertation is based on the development of the new anchorage strength model using genetic programming (Kalfat and Al-Mahaidi, 2015). For the readers there are headings and sub headings have been provided throughout the dissertation. The headings and the subheadings of the dissertation are apt for the purpose of the research study and rightly describes the content but there is possibility to improve the headings and the sub-headings by making them more concise and relevant. Throughout the dissertation it can be seen that the theories and conclusion have properly supported by the relevant theories and proper explanation is provided for the interpretation of the results obtained in the research study and are supported by facts from practical data and the research work carried out by the earlier authors. Going through the complete research study it can be said that except of certain modifications the paper ‘hold together’ as a coherent and complete piece of work.
In the abstract the author has clearly described the purpose of the research study i.e to use available experimental data on patch-anchored joints to develop a new anchorage strength model using genetic programming hence the main purpose of the abstract which is to inform the readers what the research study is all about is served by this abstract (Kalfat and Al-Mahaidi, 2015). Though the introduction defines the benefit of the new model but it should have provided a view of the various techniques and processes specific to this field of study that was used during the research study. Though the introduction is sufficient for this research study and properly sets the scene for the further research. The outline for the development of the model is not clearly stated in the introduction. Further the introduction lacks in one more area, the brief of the conclusion is not provided in the introduction. The introduction does not describe whether the end result that was obtained satisfied the purpose of carrying out the research study.
Abstract
The introduction of the chapter was inadequate the writers have not clearly explained the hypothesis, aims and objectives of the research study clearly and separately. In the first chapter the author has primarily concentrated on the background information and the summary of the experimental work that has been done on the topic of the patch-anchored joints. But the chapter does not describe the background concepts and the information on the basis of which the experiment was initiated by the researchers. In order to understand the main purpose of the research study not much of an effort is required and the summary of the research study clearly describes the path that has been taken by the researchers in order to carry out the research study. The first chapters lacks in the adequate description of the background to the problem which lead to the investigation . It only gives a gist of the problem. The back ground and the rationale does not clearly define the purpose of the experiment as the writer has himself said that the research work was carried out in a very limited data sets and further experiments are required the model to be modified to account for the strength of the saturant adhesive, which was found to influence the failure mode of the anchor and the overall strength achieved. This clearly shows that the purpose of the carrying out the research activity was not completely successful. Though the researchers have given proper explanation about the various independent and the dependent variables and established a proper relationship in order to attain the results, they have failed to set up proper research questions before carrying out the research activity (Her and Liu, 2012). They have primarily focused just on the development of the model. Since no clear hypothesis is provided by the authors in the dissertation thus it is not possible to test the hypothesis of the research topic. The writers have defined the scope and the limitations of the research study in the first chapter which helps the readers to understand the quality of the research study hence it can be said that the writers were honest in their assessment of their research study. The limitations of the research study were somehow relevant and in congruence with the conclusion of the research study. The overview of the dissertation is given in the first chapter and it clearly describes the various stages that has been followed for the development of the new model for the patch-anchored joints. The objectives have not been clearly identified but since the steps of the process followed in the research study has been explained in detail along with the purpose of carrying out those steps thus it is possible to acknowledge the objectives of the research study from this section.
First chapter
There were several questions were raised on the literature review. Not many citations were included by the authors in the literature review and many citations were repeated throughout the research study. The literature review is not confined to specific section and is spread to the entire dissertation as various other research works has been quoted and cited in the subsequent sections of the research study. the literature review is though relevant to the scope and aim of the dissertation (Budka, 2009). All the citations have been properly referenced but there is a requirement for more citations. The entire dissertation was based on just thirty references. Since there are multiple works which has been done either on the same topic or on the allied topics thus it is important that the authors should have used more scholarly works in their research study so as to gain more insight into the research works that has been carried out on the topic. Further most of the scholarly work that has been used in the dissertation is very old mainly in the 1990s. And most of the references that have been used are based on the journals and very few references are given from the websites and other sources (Kalfat and Al-Mahaidi, 2015). The literature review does not relate to all the topics of the research study. Further there are no significant value judgments of the literature nor have the findings of the literature review of the different works been clearly stated in this section.
The proposed methodology that has been used by researchers in the research study is very hard to follow. It would have been better if the researchers have described properly the methods. The extent of the data collected is limited but it served the scope of the research study (Kalfat and Al-Mahaidi, 2015). Most of the data that has been collected have been from the secondary sources that is most of the datasets were collected from the published data sets. Thus most of the data were collected from the secondary sources and there was either nill or few data used in the research study which were collected from the primary data sources. The sample size of the data is sufficient to draw a significant conclusion. The methodology that has been adopted is proper and appropriate for attaining the purpose behind carrying out this research activity.
There were no significant alternative methodologies considered in the research study as the research study was significantly based on the application of the genetic programming in the development of model frp-to-concrete patch-anchored joints (Anch and Laposky, 2000). The choice for selecting a particular method of research was justified beforehand and the instruments that has been used in the research study is appropriate for the research study. There were various evidence which shows that the instruments were calibrated such as Numerical finite element simulations were conducted which were able to capture the pre-peak and post-peak response of the patch-anchored joints to a high level of accuracy, once calibrated with the numerical data
Literature Review
The research has clearly stated the outcomes of the research study. The outcomes of the research are:
The average absolute errors (AAEs) for each model clearly indicate that the GP model is superior in accuracy, resulting in an AAE value of 6.7% compared with 11.04% for the SE model (Kalfat and Al-Mahaidi, 2015).
The maximum error exhibited by both models was _19.6% and _35.7% for the GP and SE models (Kalfat and Al-Mahaidi, 2015).
Parametric studies on both SE and GP models highlighted similar trends in parametric behavior between the two models. However, both equations should be used within the range of parametric values used to derive the expressions (Kalfat and Al-Mahaidi, 2015).
The results thus given shows that the researcher atleast able to satisfy the major party of the scope of the research. The results section has properly described the graphical and the statistical process that was used to represent the data.
Conclusion and recommendation:
the conclusion section states that the research study presented the development and assessment of a new model for FRP patch-anchor strength prediction based on a generic programming (GP) modeling approach. It recommended to use wide range of data sets to develop a more holistic model (Kalfat and Al-Mahaidi, 2015).
